English Introduction
The WZP-621B thermoresistance is a high-precision temperature measuring element specifically designed for power station temperature measurement requirements. It uses high-quality platinum wire as the temperature-sensing element, which provides good linearity and stability, and can accurately measure the temperature range from -200℃ to 850℃.
The structure of the WZP-621B thermoresistance is compactly designed with a high protection rating, making it suitable for the complex operating environment of power stations. Whether it is in the high-temperature and high-pressure steam turbine or the low-temperature cooling system, it can work stably and reliably.
The junction box of this thermoresistance is fully sealed, effectively preventing dust and moisture ingress to extend its service life. The lead wires are made of materials that are resistant to high temperatures and corrosion, ensuring stable and accurate signal transmission. The installation methods are flexible and diverse, with options such as threaded connection and flange connection, allowing users to choose according to the on-site requirements.
With high temperature measurement accuracy and good repeatability, the WZP-621B thermoresistance can provide reliable data support for power station temperature monitoring. It helps users to keep track of the equipment operating conditions in real-time, optimize operating parameters, and ensure the safe and efficient operation of the power station.
